Hello life_ender: Well... from my non-professional perspective, I would say the chances are it's the med's you're on that are the cause of this, especially given that it came on so quickly. However it is also true that worry over impotence can itself escalate the problem. It becomes something of a self-fulfilling prophecy, so to speak. You have one instance where you have difficulty... this causes you to start worrying about it... & that worry just helps to ensure that you're even more likely to have additional problems as time goes on. Perhaps the trouble you're experiencing is a combination of both med's plus the anxiety you've developed around this. At last these are my thoughts with regard to your post.
